Abstract

A communication device includes a first substrate including antennas including a first antenna and a second antenna, and a battery including a principal surface and being used as a power source of a circuit connected to the antennas. The battery, when viewed in a direction perpendicular or substantially perpendicular to the principal surface of the battery, is disposed between the first antenna and the second antenna, and a portion or all of the first antenna and the second antenna overlap with the battery, when viewed in a direction in parallel or substantially parallel to the principal surface of the battery.

First claim

What is claimed is:

1. A communication device comprising:
a first substrate including a plurality of antennas including a first antenna and a second antenna; and
a battery including a principal surface and being used as a power source of a circuit connected to the plurality of antennas; wherein
the battery, when viewed in a direction perpendicular or substantially perpendicular to the principal surface of the battery, is disposed between the first antenna and the second antenna;
a portion or all of the first antenna and the second antenna overlap with the battery, when viewed in a direction in parallel or substantially parallel to the principal surface of the battery;
the first substrate includes a plurality of flat portions including a first flat portion and a second flat portion, and a bent portion that connects flat portions that are adjacent to each other;
the first antenna is disposed in the first flat portion; and
the second antenna is disposed in the second flat portion.

2. The communication device according to claim 1 , wherein
the first substrate includes a multilayer body of insulator layers; and
each of the first flat portion and the second flat portion includes a greater number of insulator layers than the bent portion.

3. The communication device according to claim 1 , wherein the first substrate includes the battery or a battery holder that holds the battery.

4. The communication device according to claim 1 , further comprising a second substrate that is different from the first substrate, wherein the second substrate includes the battery or a battery holder that holds the battery.

5. The communication device according to claim 1 , wherein a use frequency band of the first antenna is substantially an integral multiple of a use frequency band of the second antenna.

6. The communication device according to claim 1 , wherein the first antenna and the second antenna are antennas to perform wireless LAN communication using a same or substantially a same frequency band.

7. The communication device according to claim 1 , wherein at least one of the first antenna and the second antenna include a directivity that directs a direction away from the battery.

8. A communication device comprising:
a first substrate including a plurality of antennas including a first antenna and a second antenna; and
a battery including a principal surface and being used as a power source of a circuit connected to the plurality of antennas; wherein
the battery, when viewed in a direction perpendicular or substantially perpendicular to the principal surface of the battery, is disposed between the first antenna and the second antenna;
a portion or all of the first antenna and the second antenna overlap with the battery, when viewed in a direction in parallel or substantially parallel to the principal surface of the battery;
the first substrate includes a flat portion, and a bent portion continuous from the flat portion; and
at least one of the first antenna and the second antenna is disposed in the bent portion.

9. The communication device according to claim 8 , wherein
the first substrate includes a multilayer body of insulator layers; and
the flat portion includes a greater number of insulator layers than the bent portion.

10. The communication device according to claim 8 , wherein the first substrate includes the battery or a battery holder that holds the battery.

11. The communication device according to claim 8 , further comprising a second substrate that is different from the first substrate, wherein the second substrate includes the battery or a battery holder that holds the battery.

12. The communication device according to claim 8 , wherein a use frequency band of the first antenna is substantially an integral multiple of a use frequency band of the second antenna.

13. The communication device according to claim 8 , wherein the first antenna and the second antenna are antennas to perform wireless LAN communication using a same or substantially a same frequency band.

14. The communication device according to claim 8 , wherein at least one both of the first antenna and the second antenna include a directivity that directs a direction away from the battery.

15. A communication device comprising:
a first substrate including a plurality of antennas including a first antenna and a second antenna;
a second substrate that is different from the first substrate; and
a battery including a principal surface and being used as a power source of a circuit connected to the plurality of antennas; wherein
the battery, when viewed in a direction perpendicular or substantially perpendicular to the principal surface of the battery, is disposed between the first antenna and the second antenna;
a portion or all of the first antenna and the second antenna overlaps with the battery, when viewed in a direction in parallel or substantially parallel to the principal surface of the battery;
the second substrate includes the battery or a battery holder that holds the battery; and
a surface of the first substrate on which the first antenna and the second antenna are disposed faces a surface of the second substrate on which the battery or the battery holder is mounted.

16. The communication device according to claim 15 , wherein a use frequency band of the first antenna is substantially an integral multiple of a use frequency band of the second antenna.

17. The communication device according to claim 15 , wherein the first antenna and the second antenna are antennas to perform wireless LAN communication using a same or substantially a same frequency band.

18. The communication device according to claim 15 , wherein at least one of the first antenna and the second antenna include a directivity that directs a direction away from the battery.
